I don't know if you wcould call this THE signature hole for the course (as there are a lot of great holes), but it's definitely one that stands out in my mind when I think about Circle R. It's a pretty short anhyzer shot that you could make with a putter, but the water definitely makes it a little intimidating.

I took this pic from someone's Myspace...last time I played it the water was noticeably higher....tried a forehand with a Rhyno and dumped it right into the waterfall

I'll have to make several posts for all of the signature holes here in Northern California, but I'll start with the best of them first(imho):

Delaveaga Park, Santa Cruz, CA - Hole #27 - "Top of the World"

580 feet away, something like a 100 foot drop. It's hard to pick out the basket from this photo, but if you see the eroded away area on the grass far below where this shot was taken, the basket is in the circular portion that's up and left from the path-looking erosion.

Beyond the basket and to the left is the entrance road to the park, and road and beyond is OB. You'd think that because it's more than 600 feet away it wouldn't come into play, but I have thrown OB with a Roc on more than one occasion, and the parking lot is just beyond the road. When you're getting out of your car, it's important to keep an ear out for a distant shout of 'PAARKKIIINGG LOOOTTTT!'

The view from the tee box is amazing- the course is only a few miles from the Pacific, and there are huge coastal redwoods all around. Truly spectacular.

Golden Hills Disc Golf Course in Christiansburg, VA is my home course and at least in my opinion hole number 3 would probably be the most memorable hole visually. The hole is roughly 160-175 feet long and drops 62 feet over that distance. While the hole is fairly easy to birdie, especially with a thumber, it can become quite an adventure if you go for the ace run with a backhand shot and leave it a little high as the terrain continues to drop beyond the basket. I've seen people throw a good 100 or more feet past the basket if they throw the shot a little hard and not at a downward angle. Aces, birdies, pars, bogeys and occasionally worse all make an appearance at this hole.

From the bottom of the hill. That narrow bike trail leads right to the pin if you can't see it.

The elevation drop is about 35' down at about a 70 degree incline. When the green fills in you have about a 6' window down the hill. No O.B. but if you go off the fairway anywhere, good luck finding your disc. I've never seen a birdie here.
